This cleaner source of electricity comes from a newly constructed renewable energy facility at the Potrero Hills Landfill in Suisun City, Calif.

DTE Biomass Energy, the developer and operator of the project, declared commercial operation of the 8-megawatt facility at the landfill, which is operated by Waste Connections Inc. of The Woodlands, Texas. Gas generated at the landfill will be used to produce renewable energy for Pacific Gas & Electric under a long-term purchase agreement.
